Catherine Middleton, Duchess of Cambridge, in one of the dresses that sparked concern about her thin frame

Seven weeks into her new life as a royal, the Duchess of Cambridge looks thinner than ever. But has she gone too far?

Scrutinized by the British press – with various tabloids calling her the “disappearing Duchess” and “not so weighty Katie,” Princess Kate’s super-slim figure continues to raise eyebrows as fears about how she’s coping with the pressure of being royalty’s hot new star take centre stage.

The most concerned about Kate’s weight loss is the man who loves her most, Prince William. According to the UK’s Now magazine, “William wants Kate to put on a few pounds.” The newlyweds, who have always shared a passion for food and sharing meals with friends, have been known to have a taste for the exotic, with the Duchess even feasting on wild boar while her husband prefers crocodile.

Sources close to the royal family insist that it is nerves about her responsibilities as the future Queen of England, not self-denial, that are keeping the Duchess of Cambridge looking slimmer than ever. “I don’t imagine she likes for one minute all the scrutiny about her weight and what she’s wearing,” royal expert Sean Smith tells WHO in it’s new issue.
